StreamAllMids - Stream All Perp Mid Prices
Subscribe to current full mid-price maps for the default Hyperliquid perp DEX over the V3 gRPC API.
StreamAllMids sends the complete default-DEX perp mid-price map as a live Info-derived view rather than a block-cadence stream.
Request and opening behavior
The request has no fields. A warm subscription immediately receives the current map, then receives a complete replacement when its values change. time identifies when the endpoint made the update available, not a block or upstream timestamp.
For a bookless market, the map uses the last-trade fallback. Every frame supersedes the previous map.
Delivery and recovery
Subscriber lag drops obsolete maps in-band. An upstream outage produces silence rather than closing an established stream. UNAVAILABLE means a new subscription has no fresh data, FAILED_PRECONDITION means the stream is unavailable on this endpoint, and ABORTED means its state reset. See the shared market-stream contract for common errors.
